Abstract

To address the problems of unbalanced label distribution, excessively long medical record text and large label space in the international classification of diseases(ICD) coding classification task, this paper proposed an ICD coding classification method based on data augmentation and dilated convolution. Firstly, this method introduced the pre-trained model BioLinkBERT, trained in the biomedical domain using unsupervised learning, to alleviate the domain mismatch problem. Secondly, it applied the Mixup data augmentation technique to expand the hidden representations, thereby increasing data diversity and improving model robustness for classification, addressing the problem of imbalanced label distribution. Finally, the model effectively captured long-range dependencies in the text data using multi-granularity dilated convolution, avoiding the impact of long input text on the model's performance. The experimental results demonstrate that the proposed model achieves notable improvements over the baseline model on two subsets of the MIMIC-Ⅲ dataset when compared with various methods. Specifically, the F1 scores and precision@k values improves 0.4% to 1.5% and 1.2% to 1.6%, respectively. Therefore, this study provides an effective solution to solve the challenges of ICD coding classification.
